Re: Tire Recommendations?

I put a set of Diamondback radials on my Series 23 last year after lots of research. Diamondback offers a slightly taller profile tire (I think it is series 78) that duplicates both the diameter and the width of the original tires. Also the tread pattern looks vintage correct. I chose these because of the original looks and the proper diameter. I get slightly less rpm on the freeway with the proper diameter tires rather than 75 series tires. The disadvantage of the taller tire is the stiffness. Since these are made using a truck tire the construction is stiffer and thus the ride is slightly harder than a lower profile passenger tire. That feels OK to me and I love the rest of the advantages.

The problem with lower profile tires is the width is too large using correct diameter tires. If you use tires with a width that clears the body, the diameter is less compared to original.
